Can you please code in a function for the car to ignore code P0560? "low voltage to ECU"


I keep getting this, repeatedly, and I don't know why. Car cranks and drives just fine.

I'd really love if the unit could just tell the computer to ignore that code.
Yeah the codes are there for a reason. Removing the emission codes make sence since you get them from no longer having a cat. If you are getting a low voltage to ECU code then something may be wrong and needs to be looked at. This is not a common code people get after tuning.

Did you ever take it in for that? We try not to just add code disables as patches for actual issues.
yeah, I was thinking the same. Wonder if he has that harness issue that was recalled...
But yeah, I'd take it in for warranty. It may just be coincidental it happened around the time he flashed the ECU.

Totally off topic, I'm going to probably need to switch to the dampening calibration. The temps have dropped here and the car is a monster, lol. Spinning/wheel hopping in 3rd is just crazy when I stomp on the gas.

Have not yet. No other mods. Only mishi catch can, Ktuner, and USR downpipe.

I plan to take it in after this track season is over. Probably early December.

Yeah I am definitely going to get it checked out, it just happens like every other time I start the car. Then I have to shut it down, clear the code, then crank it again.

Obviously on track days that is VERY annoying to have to do when I start the car on pit road. I'd just let the code ride out but it disables rev match which I do use depending on what track I'll be at.


I more just wanted the disable as a stop-gap measure until I could get it checked out. The car seems perfectly healthy otherwise. Battery is totally fine, alternator voltage is totally fine. It's just right at the moment that the car cranks that the voltage drops enough to throw the code, and it seems to be more common the hotter it gets. For all I know this existed from day one and didn't show itself until it got really hot outside.


Thanks guys.

USR FTFW LOL


Not sure if you're implying that anything USR is causing this or not, but I can assure you it isn't. I was on the USR downpipe with zero issues for quite a while before this code popped up.

I never once got a CEL when I just had the USR downpipe. Their stuff is quality and so is the work.

Low/intermittent voltage to the ECU cost us a motor on one of our race cars a year or so ago. The ECU would cut out due to vibrations, which would cause the fuel to stop flowing and timing to get out of whack. That caused detonation, which eventually ate a valve. The valve travelled through the rest of the engine after being sucked back up through the intake.

Don't put off bringing it in for power issues, especially to the ECU.

Hey no! I have the USR Dp installed too w/ktuner basemap no issues. Im just implying the dp rocks.

I will definitely get it checked out.

But to reiterate, it's only during cranking that it throws the code. It has never thrown the code during driving.

That is extremely odd.

Ktuner team. Any info or update on the stage 2? Will it require any supporting mods?
